All Implemented Interfaces:
WorkManager
```
public class SimpleTaskWorkManager
extends Object
implements WorkManager
```
Simple JCA 1.5 WorkManager implementation that delegates to a Spring TaskExecutor. Provides simple task execution including start timeouts, but without support for a JCA ExecutionContext (i.e. without support for imported transactions).
Uses a SyncTaskExecutor for doWork(javax.resource.spi.work.Work) calls and a SimpleAsyncTaskExecutor for startWork(javax.resource.spi.work.Work) and scheduleWork(javax.resource.spi.work.Work) calls, by default. These default task executors can be overridden through configuration.
NOTE: This WorkManager does not provide thread pooling by default! Specify a ThreadPoolTaskExecutor (or any other thread-pooling TaskExecutor) as "asyncTaskExecutor" in order to achieve actual thread pooling.
This WorkManager automatically detects a specified AsyncTaskExecutor implementation and uses its extended timeout functionality where appropriate. JCA WorkListeners are fully supported in any case.

Method Detail

setSyncTaskExecutor
```
public void setSyncTaskExecutor(TaskExecutor syncTaskExecutor)
```
Specify the TaskExecutor to use for synchronous work execution (i.e. doWork(javax.resource.spi.work.Work) calls).
Default is a SyncTaskExecutor.

setAsyncTaskExecutor
```
public void setAsyncTaskExecutor(AsyncTaskExecutor asyncTaskExecutor)
```
Specify the TaskExecutor to use for asynchronous work execution (i.e. startWork(javax.resource.spi.work.Work) and scheduleWork(javax.resource.spi.work.Work) calls).
This will typically (but not necessarily) be an AsyncTaskExecutor implementation. Default is a SimpleAsyncTaskExecutor.

                    throws WorkException
```
Execute the given Work on the specified TaskExecutor.
Parameters:
taskExecutor - the TaskExecutor to use
work - the Work to execute
startTimeout - the time duration within which the Work is supposed to start
blockUntilStarted - whether to block until the Work has started
executionContext - the JCA ExecutionContext for the given Work
workListener - the WorkListener to clal for the given Work
Returns:
the time elapsed from Work acceptance until start of execution (or -1 if not applicable or not known)
Throws:
WorkException - if the TaskExecutor did not accept the Work
